Part numbers:
52380-42082 (rear)
52380-42071 (front)
The rear diff mount is cake. Put a jack on the diff, remove 4 bolts. Replace mount.
The front mount can be replaced in under an hour. I did it by disconnecting the muffler, moving the exhaust over. Unbolting the sub-frame from the car. Remove one trailing A-arm to give me a little more flexibility. Remove the rear mount. And remove drive shaft (if I recall right). The nose of the diff will come down enough to get at it...
Replacing one mount works if your rear just started clunking. If it's been clunking a worn out rear mount literally wears the rubber (too much throw) in the front mount...
I've reproduced these and with the help of some Rav4world members, went through the process of installing bushings... Eventually we decided that most people want to replace the entire mount, as shops were charging more than what I charge for the entire mount, just to replace the bushings...
